Re: Why did NVIDIA skip the revision of Direct X 10.01 on their 9800 GTX/GX2/GTX 260/

I think the crux of the issue is that DX10 really hasn't brought the "performance improvements" that Microsoft claimed it would.. at least not on a grand level. But with DX10.1, it's showing tangible benefits that have been verified by both developers and the gaming community, so there's motivation to use it as long as the hardware support is there.
